897800 divided by 80 
We're looking to find how many times 80 goes into 897800.

Moving on to step 1:
8 divided by 80 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 80

Step 2:
If we divide 89 by 80, we get 1 and a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 9 after subtracting 80 from 89.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 80

Step 3:
When dividing 97 by 80, we get 1 with a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we take 80 away from 97, we end up with 17.
Grab the next digit (8) from the dividend, add it to 17, then carry on: 178 / 80

Step 4:
80 goes into 178 2 times with a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 112.0
If we take 160 away from 178, we end up with 18.
Grab the next digit (0) from the dividend, add it to 18, then carry on: 180 / 80

Step 5:
80 can be fit into 180 2 times, resulting in a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 1122.0
If we subtract 160 from 180, we get 20.
Take the next digit (0) from the dividend and append it to 20, then repeat: 200 / 80

Step 6:
200 divided by 80 is 2 with a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 11222.0
Subtract 160 from 200 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 7:
400 divided by 80 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 11222.5
Deduct 400 from 400 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
If we divide 0 by 80, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 11222.5
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
80 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 11222.5
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 11222.5, and the remainder is 0.0.
